Commercial Painting in Canada: Basics, Licensing Requirements, and Key Facts
Commercial painting looks simple from the outside: crews, sprayers, and a lot of drop cloths. On site, it’s a different picture. The work blends surface science, safety planning, project phasing, and strict compliance with building and fire codes. If you own or manage property in Edmonton — from a Whyte Avenue retail build-out to a west-end office, a Strathcona warehouse, or a food-grade facility in Nisku — the difference between a standard paint job and a professional commercial finish shows up in durability, clean lines, and zero disruption to your operations.
This article breaks down what commercial painting includes, how it differs from residential work, and what licensing and qualifications matter in Alberta and across Canada. You will also see where commercial painting services add value in budgeting, scheduling, warranty protection, and compliance. If you need pricing for a specific site, our team at Depend Exteriors can assess your building envelope, coatings, and timelines and provide a clear plan.
What counts as commercial painting
Commercial painting covers interior and exterior coatings for non-residential buildings. Think offices, retail units, schools, hospitals, restaurants, multi-family common areas, light industrial spaces, and warehouses. It also includes specialized substrates like tilt-up concrete, EIFS, stucco, masonry, steel, and aluminum storefront systems.
In practical terms, commercial painting services include surface assessment, preparation, priming, application of finish coats, and protection or re-coating plans. The scope often extends to sealants, minor repairs to substrates, line painting in parkades, and protective coatings such as epoxies or urethanes in high-wear zones. On exterior envelopes, it may also include elastomeric coatings for hairline crack bridging on stucco or block walls, anti-graffiti clear coats along alleys, and corrosion-control systems on exposed steel.
The working model is different from a residential repaint. Work hours often shift to evenings or weekends to keep tenants open. Crews must plan lift access, barricades, and public safety. For high-traffic areas, the team selects coatings with fast recoat or overnight cure to hand back spaces without sticky floors or lingering odour.
Where commercial jobs differ from residential projects
The differences show up in five places: scale, substrate variety, coating chemistry, scheduling, and documentation. Commercial spaces mix materials that do not show up in houses. For example, acrylic direct-to-metal coatings for doors and hollow metal frames, two-component epoxies for mechanical rooms, alkyd rust-inhibiting primers on steel stairs, and elastomerics on CMU. Dryfall coatings reduce overspray mess https://dependexteriors.com/our-services/commercial-painting/ in high ceilings. Intumescent fireproofing may be required on structural members.
Scheduling is more rigid. Tenants have opening hours tied to sales. Hospitals and schools set tight shutdown windows. Property managers need noise control, hoarding, and formal safety paperwork. Documentation matters: safety data sheets on site, colour schedules for multiple units, lift operator certificates, and permits for lane closures or aerial work.
Finally, warranty expectations are different. Owners expect coatings that hold up to cleaning, salt, UV, and traffic. That requires correct surface profile, moisture checks, and manufacturer-specified film thickness, not just a “good look” at handover.
Common surfaces and the right prep
Durability starts with preparation. In our Edmonton climate, failures trace back to poor prep more often than bad paint. Freeze-thaw cycles, road salt, and low humidity indoors all stress coatings. Here is how we approach common substrates:
Concrete and CMU block. We test for moisture transmission, efflorescence, and pH. New concrete needs cure time, usually 28 days, though some primers handle earlier application. We may diamond grind or acid etch floors before epoxy. On exterior block, we address hairline cracking and install elastomeric systems to shed water.
Stucco and EIFS. We pressure wash at controlled PSI, check for chalking with a cloth test, and seal cracks. Chalking stucco needs a bonding primer. Elastomeric coatings bridge micro-cracks and lengthen maintenance cycles, a smart move on south and west elevations exposed to UV and wind.
Metal. For galvanized steel and aluminum storefront, we degrease, abrade lightly, and use an appropriate primer to avoid adhesion failure. On ferrous metals, we remove rust to a sound edge and use rust-inhibitive primers before finish coats.
Drywall. In offices and retail, proper level-4 or level-5 finishing shows under flat LEDs. We backroll the primer to create a uniform texture and avoid flashing.
Wood and millwork. In restaurants and retail, we often shift to waterborne enamels with harder resins to cure faster and reduce odour, then sand between coats for a tight finish.
Each surface has its failure modes: blistering from trapped moisture in concrete, alligatoring on old alkyds under fast-drying acrylics, or peeling on unprimed galvanized. A good estimator spots these risks during the walkthrough and builds the right prep into the quote.
Coating systems that suit Edmonton buildings
Product selection should match usage, cleaning frequency, and code requirements. Across Edmonton and the surrounding area, we see strong outcomes with these pairing strategies:
Interior offices and corridors. High-build acrylics with scrub ratings that handle daily cleaning. Eggshell in corridors; satin on doors and frames. Formaldehyde-free, low-VOC lines help indoor air quality, which matters during winter when buildings run in recirculation.
Healthcare and clinics. Zero-VOC with antimicrobial additives where allowed, and a satin or semi-gloss to withstand disinfectants. We coordinate work phasing to keep air exchange rates adequate.
Restaurants and food prep. Two-component epoxy on back-of-house walls, epoxy or urethane on floors with slip resistance added. Grease-prone ceilings use washable acrylics or specific kitchen coatings.
Parkades and mechanical rooms. Moisture-tolerant epoxies, alkyd primers on steel, and high-visibility striping paints. Chloride exposure and freeze-thaw are constant. We plan recoat windows to reduce downtime.
Exterior stucco and block. Elastomeric topcoats over masonry primers. In our winter climate, we aim for late spring through early fall application windows, and we monitor overnight lows to avoid dew-point traps.
Exterior metals and trims. Urethane-modified acrylics for UV resistance, direct-to-metal for quick turnarounds. On corrugated panels, spray application with proper masking saves days.
This balance keeps spaces looking fresh while holding maintenance costs down.
Safety, staging, and working while you stay open
Safety and access planning often set the schedule. On a downtown mid-rise, we coordinate with property management to stage swing stages or boom lifts, set up sidewalk sheds, and meet municipal permit requirements. Inside, we control dust and odour with negative air and zipper walls, then phase floors or zones to keep tenants moving. Night work solves the most conflict. For a south Edmonton grocery store repaint, we ran a 10 pm to 6 am shift and returned the aisles clean at opening. The paint never became the story for customers.
On industrial interiors, lockout/tagout matters near moving equipment. We work under CSA and OH&S standards, and our crews maintain fall protection, aerial work platform tickets, and WHMIS training. Documentation isn’t theatre; it keeps your insurance coverage clean and your tenants confident.
How commercial bids are built
A professional quote should explain surface prep, primer type, finish coats, application method, number of coats, and the conditions required for application. It should list exclusions such as major carpentry, mould remediation, or asbestos mitigation, and it should describe hours of work, protection measures, and waste handling. On exteriors, the quote should specify access equipment like lifts and whether curb lane closures are included.
Pricing reflects four inputs: square footage, substrate condition, coating chemistry, and access. A clean, smooth office repaint might run at a lower cost per square foot. A block-walled warehouse with oil contamination or a parkade ceiling with chlorides will cost more due to degreasing, priming, and specialized materials. Expect a wide range. As a rule of thumb in Edmonton, interior office repaints can land in a mid-teens to low-twenties per square foot for labour and materials on smaller suites, while heavy-prep industrial spaces move higher. For exteriors, lift time and weather delays matter more than many owners expect; a week of wind and rain can push dates and labour.
We recommend investing in test patches. On a 1960s block building in central Edmonton, we ran three elastomeric samples side-by-side through a freeze-thaw cycle. The client could see the difference in bridging and sheen retention before approving the full scope.
Warranty and maintenance planning
A coating system lasts longer with a simple maintenance plan. Annual rinsing of exteriors reduces grime and salt that erode films. Interior high-touch areas benefit from a quick touch-up once a year to keep edges crisp. If we install an elastomeric or epoxy, we document batch numbers and colour codes so future touch-ups match.
Warranties vary by product and exposure. On interior offices with acrylic finishes, two years on labour and materials is common. On exteriors, coverage reflects exposure and substrate movement; three to five years on elastomeric systems is typical for labour with manufacturer backing on material performance. The fine print matters: improper cleaning chemicals void warranties, and ponding water or leaks need to be corrected at the building envelope, not with paint.
Licensing, permits, and compliance in Canada and Alberta
Paint contractors in Canada operate under provincial rules. Alberta does not issue a “painter’s licence” in the same way it licenses electricians or plumbers, but commercial painting requires business registration, tax compliance, safety training, and often municipal permits for work that affects public space. Property managers and GCs expect specific documentation.
Here is what clients should look for in Edmonton and across Alberta:
- Business registration and WCB coverage. Any legitimate commercial contractor in Alberta carries Workers’ Compensation Board coverage and provides a WCB clearance letter on request. This protects owners from liability if a worker is injured on site.
- Liability insurance. Standard practice is $2 million to $5 million in commercial general liability. For high-rise exterior work or industrial facilities, higher limits may be required. Always ask for a certificate of insurance naming your company as an additional insured for the project term.
- Safety training and COR/SECOR. The Certificate of Recognition (COR) or Small Employer COR shows a safety program audited to provincial standards. Crew members should also hold WHMIS, fall protection, and aerial work platform certificates where applicable.
- City permits and bylaws. Exterior projects that occupy sidewalks, alleys, or curb lanes in Edmonton require road-use permits and traffic management plans. Noise bylaws set timing for power washing or early-morning work; plan schedules accordingly.
- Building code and fire ratings. If a specification calls for intumescent or fire-resistive coatings, the contractor must use listed products and follow the manufacturer’s film thickness and inspection requirements. Documentation includes dry-film thickness readings and product batch logs.
Licensing rules differ by province. For example, Quebec and parts of Ontario regulate trades in ways Alberta does not. Nationally, compliance with WHMIS, hazard assessments, and use of safety data sheets is consistent. The takeaway: verify coverage and competency rather than chasing a “painter’s licence” that does not exist in Alberta. A reputable firm will provide WCB, insurance, COR or SECOR status, and worker certifications without delay.
Environmental and indoor air quality considerations
Most modern commercial paints are low-VOC, and many are zero-VOC. That said, the actual odour and off-gassing depend on resin systems, not only VOC numbers on the can. For occupied spaces, we select acrylics with fast cure and schedule after-hours work with extra air changes. On schools and clinics, we use lines that meet or exceed Green Seal or GREENGUARD criteria and provide the data sheets for your records.
Wash water management and overspray control are environmental basics. On exteriors, we capture or direct wash water to approved drains, never to landscaping or storm sewers without control. Dryfall coatings help keep overspray from settling on cars or neighbouring façades in tight urban sites. Edmonton’s dry, windy conditions raise drift risk; we plan spray windows early morning or late evening when winds are calmer, or we brush and roll along sensitive elevations.
Timelines: what is realistic in our climate
Edmonton’s short painting season for exteriors runs roughly from late May through September for most coatings, based on night temperatures and dew points. Cold nights can trap moisture under films and cause early failure. Elastomerics and some masonry primers need higher minimum temperatures. We watch the forecast and shift sequencing to elevations that catch sun earlier on cool days.
Interiors run year-round. For a 10,000-square-foot office repaint, we often set a two-week schedule with evening shifts and hand back finished areas progressively. For retail build-outs, we compress schedules around millwork and flooring so final paint lands after heavy trades but before opening. A candid schedule upfront keeps tenants calm and prevents surprises.
How colour and sheen choices affect maintenance
Beyond branding, colour and sheen affect how a building wears. Dark exteriors look sharp but absorb more heat and show salt and dust. In Edmonton winters, that can highlight drip marks along parapets. Lighter mid-tones hide dust and reduce thermal stress. On interiors, eggshell walls hide scuffs better than flat, and satin or semi-gloss on doors and frames stands up to cleaning. In stairwells and parkades, higher sheen levels improve light reflectance and safety.
We encourage sample walls. A 4-by-4-foot sample in the actual light beats any fan deck decision. LEDs with a cool temperature can push greys toward blue; natural light can warm them. Twenty minutes with samples can prevent years of “almost right.”
Budget strategies that don’t backfire
Cutting prep to save money almost always costs more later. There are better places to manage budget pressure:
- Keep existing colours when possible to avoid extra coats. A sharp refresh in the same colour often looks like a full renovation.
- Limit accent walls. One or two strong accents per floor create impact without multiplying colour changes and labour time.
- Group work by access. If a boom lift is on site, tackle all high elevations in one mobilization rather than splitting visits.
- Use high-build acrylics in busy corridors. They cost more per gallon but reduce repaint cycles and labour over three to five years.
- Phase common areas in off-hours to avoid tenant disruption fees or penalties.
These choices protect the finish and keep your operations stable.
What to expect during a Depend Exteriors project
We start with a site walk. We note substrates, access, tenant schedules, and pain points like moisture, chalking, or rust. You get a clear scope that spells out prep, products, coat counts, protection, and schedule. We provide WCB and insurance certificates and list our safety lead and training credentials.
Before mobilization, we coordinate colour approvals and any permits for lifts or lane use. On interior work, we set up protection and signage, confirm after-hours access, and create a floor-by-floor sequence with your team. During the job, a site lead updates you daily with progress photos and next steps. We complete a punch walk, correct items promptly, and leave touch-up paint labelled with codes and locations.
After turnover, we provide a brief maintenance sheet and a warranty document with product details. If anything feels off in the first weeks — a door edge that rubs, a patch that needs an extra pass — we respond quickly. That is part of a proper commercial service relationship, not a favour.
Local context: Edmonton neighbourhoods and building types
We have worked across Edmonton and the surrounding municipalities, and each area brings its own quirks:
Downtown and Oliver. Tight access, heavy pedestrian traffic, and strict parking control. Exterior work often needs early-morning windows and clear hoarding plans. Dryfall ceilings are common in open offices.
Whyte Avenue and Strathcona. Heritage façades with aging brick and stucco. Masonry primers and breathable coatings help retain character while shedding water. Night work keeps retail open.
South Edmonton Common and Gateway. Big box façades with EFIS and metal panels. Wind exposure is a factor; we plan spray windows and backroll to even texture. Branding colours must match strict retail standards.
West end industrial areas. Tilt-up concrete and block warehouses with forklift traffic. Epoxy floors and bumper-post protection pay off. Oil staining near docks needs aggressive degreasing and spot-priming.
St. Albert, Sherwood Park, and Spruce Grove. Mix of offices, schools, and municipal buildings. Tender work often requires COR, bond capacity, and detailed safety submissions.
Understanding these patterns helps set the right plan for your site.
FAQ: quick answers owners ask
What is the difference between commercial and industrial painting? Commercial covers offices, retail, multi-family common areas, and public buildings. Industrial focuses on plants, refineries, and heavy manufacturing with high-performance coatings and stricter surface prep standards like SSPC/NACE. Many buildings overlap. A warehouse office might be commercial inside and industrial in the loading dock.
Do you need a licence to paint commercially in Alberta? There is no trade licence specific to painters. Reputable firms carry business registration, WCB, liability insurance, COR or SECOR, and worker certifications. City permits apply for exterior access and traffic control.
Can you paint exteriors in Edmonton in October? Sometimes, if day and night temperatures and dew points cooperate and the coating permits it. Risk climbs as nights drop. We prefer spring through early fall for best results.
How long will it take? Small tenant improvements can be three to seven days. A mid-size office floor might be two weeks. Exterior façades vary from a few days to several weeks, depending on size, access, and weather.
What about odour and tenant comfort? We select low- or zero-VOC coatings and work off-hours. We isolate areas and increase ventilation. For sensitive sites such as clinics, we phase rooms and return them quickly to service.
